[0008] This invention features a support base with a positioning groove defined on its top surface. This groove allows the camera to be placed securely, preventing positional shifts during testing and reducing potential defects. With the lens facing downwards and the connector upwards, an adapter circuit board and a movable component connect the adapter circuit board to an external test box. The movable component moves the adapter circuit board closer to the support base, bringing the pin header closer to the camera. The adapter circuit board then directly contacts the camera's connector via the pin header, allowing camera data to be transmitted directly to the external test box via the pin header and adapter circuit board. This eliminates the need for electrical signal transmission components on the support base, reducing the number of circuit boards and manufacturing costs. Furthermore, it reduces the number of circuit adapters, minimizing the risk of loosening due to frequent contact between the test fixture and the camera, thus lowering the risk of circuit malfunction and improving signal transmission efficiency.

The cover restricts the base of the needle holder inside the cover, and the clearance hole can avoid the connecting part. The connecting part passes through the cover, so that the needle holder can be plugged and unplugged with the camera connector through the connecting part. Thus, when the needle holder is pulled out of the camera connector, the cover can restrict the position of the base and prevent the needle holder from falling off the adapter circuit board.

[0019] According to a first aspect of the present invention, a camera testing fixture is provided, wherein the support base has a guide groove and a clamping block slidably disposed in the guide groove, the clamping block cooperates with the side wall of the positioning groove to clamp the camera, the movable member is provided with a second abutting part, the second abutting part is used to abut against the clamping block, and a drive inclined surface is respectively provided between the second abutting part and the clamping block.

[0020] The advantages of this invention are: by setting a guide groove and a clamping block, the clamping block can slide in the guide groove. By setting a second abutment, the movable part moves closer to the support base, so that the second abutment can contact the clamping block. The second abutment and the clamping block are driven by an inclined plane, so that the clamping block slides along the guide groove. The clamping block cooperates with the side wall of the positioning groove to clamp the camera, preventing the camera from falling out of the positioning groove when the needle seat is pulled out of the camera connector, thus preventing the needle seat from being pulled out.

[0021] A camera testing fixture according to a first aspect of the present invention further includes a spring located between the guide groove and the clamping block, the spring being used to drive the clamping block to move away from the positioning groove.

[0022] The advantage of this invention is that by setting a spring, the clamping block is moved away from the positioning groove, thus moving the clamping block away from the camera.

[0042] A camera testing fixture and testing device according to an embodiment of the present invention will now be described with reference to the accompanying drawings.

[0043] Reference Figure 1 The present invention aims to provide an embodiment of a camera testing fixture and testing device.

[0044] In the construction of camera 150, camera 150 includes a body 160 and a connector 170 connected to the body 160. The body 160 is provided with a lens 161, and the connector 170 is provided with a connector 171. The lens 161 and the connector 171 are oriented in opposite directions.

[0045] This utility model provides a camera 150 testing fixture, referring to... Figure 1 , Figure 2 and Figure 3 The device includes a support base 100, an adapter circuit board 120, and a movable member 140. The top surface of the support base 100 defines a positioning groove 110 for accommodating a camera 150, with the lens 161 facing downwards and the connector 171 facing upwards. The adapter circuit board 120 is used for electrical connection with external testing equipment. The adapter circuit board 120 is provided with a pin holder 130 for abutting against the connector 171. The adapter circuit board 120 is connected to the movable member 140, which is connected to the support base 100. The movable member 140 is movable and positioned close to the support base 100 so that the pin holder 130 can abut against the connector 171.

[0046] It is understood that in this embodiment, by setting a support base 100, the top surface of which defines a positioning groove 110, the camera 150 can be placed in the positioning groove 110, ensuring that the camera 150 will not shift position during testing, reducing defects caused by testing. Furthermore, at this time, the lens 161 faces downwards and the connector 171 faces upwards. By setting an adapter circuit board 120 and a movable component 140, the adapter circuit board 120 can be connected to the external test box 330. The movable component 140 drives the adapter circuit board 120 to move closer to the support base 100, so that the pin holder 1... The pin 100 can be placed close to the camera 150, and the adapter circuit board 120 can directly abut against the connector 171 through the pin socket 130. This allows the data from the camera 150 to be directly transmitted to the external test box 330 via the pin socket 130 and the adapter circuit board 120. This eliminates the need to install electrical signal transmission components on the support base 100, reducing the number of circuit boards and manufacturing costs. Furthermore, it reduces the number of circuit adapters, minimizing the risk of loosening of the circuit adapters due to frequent contact between the test fixture and the camera 150. This reduces the risk of circuit failure and improves the efficiency of electrical signal transmission.

[0047] In some embodiments of this utility model, a hinge structure 180 is provided between the movable member 140 and the support base 100. The hinge structure 180 connects the movable member 140 and the support base 100, so that the movable member 140 can pivot relative to the support base 100.

[0048] It is understood that in this embodiment, by setting a hinge structure 180, the movable part 140 and the support base 100 are connected by the hinge structure 180. The support base is stationary, allowing the movable part 140 and the support base 100 to rotate relative to each other. The movable part 140 flips to move closer to the support base 100, so that the pin seat 130 can be connected to the connector 170 of the camera 150. The movable part 140 flips to move away from the support base 100, so that a wide space is formed above the support base 100, which makes it easier for the camera 150 to be placed in the positioning groove 110.

[0049] In some embodiments of this utility model, the positioning groove 110 includes a first groove 190 and a second groove 200. The first groove 190 is connected to the second groove 200. The first groove 190 accommodates the body 160, and the second groove 200 accommodates the connector 170.

[0050] It is understood that in this embodiment, by setting a first slot 190 and a second slot 200, the first slot 190 restricts the position of the body 160 of the camera 150, and the second slot 200 restricts the position of the connector 170 of the camera 150, thereby ensuring that the connector 170 can accurately abut against the pin seat 130.

[0051] In some embodiments of this utility model, the support base 100 is provided with a light-transmitting hole 210, which communicates with the positioning groove 110 and corresponds to the lens 161.

[0052] It is understood that, in this embodiment, by setting the light-transmitting hole 210, when the camera 150 is placed, the lens of the camera 150 can pass through the light-transmitting hole 210, and the camera 150 can take pictures and test through the light-transmitting hole 210.

[0053] In some embodiments of this utility model, reference is made to Figure 1 and Figure 4 The movable part 140 is provided with a first abutting part 220, which is located on the side of the movable part 140 near the support base 100 and is used to abut against the body 160.

[0054] It is understood that in this embodiment, by setting the first abutment part 220, the movable part 140 moves closer to the support base 100, so that the first abutment part 220 can contact the camera 150, thus preventing the position of the connector 170 of the camera 150 from shifting when the pin seat 130 contacts the connector 170 of the camera 150.

[0055] In some embodiments of this utility model, reference is made to Figure 4 The movable part 140 is provided with a cover 230 and a clearance hole 240 provided in the cover 230. The needle seat 130 has a seat 250 and a connecting part 260 connected to each other. The cover 230 accommodates the seat 250, and the clearance hole 240 is used to avoid the connecting part 260.

[0056] It is understood that in this embodiment, by setting a cover 230 and a clearance hole 240, the base 250 is connected to the adapter circuit board 120, and the base 250 of the needle holder 130 is restricted inside the cover 230. The clearance hole 240 can avoid the connecting part 260, which passes through the cover 230, so that the needle holder 130 can be plugged and unplugged into the connector 170 of the camera 150 through the connecting part 260. Thus, when the needle holder 130 is pulled out from the connector 170 of the camera 150, the cover 230 can restrict the position of the base 250 and prevent the needle holder 130 from coming loose from the adapter circuit board 120.

[0057] In some embodiments of this utility model, the support base 100 has a guide groove 270 and a clamping block 280 slidably disposed in the guide groove 270. The clamping block 280 cooperates with the side wall of the positioning groove 110 to clamp the camera 150. The movable member 140 is provided with a second abutment part 290, which is used to abut against the clamping block 280. A inclined surface 300 for transmission is respectively provided between the second abutment part 290 and the clamping block 280.

[0058] It is understood that in this embodiment, by setting the guide groove 270 and the clamping block 280, the clamping block 280 can slide within the guide groove 270. Then, by setting the second abutment part 290, the movable part 140 moves closer to the support base 100, so that the second abutment part 290 can contact the clamping block 280. The second abutment part 290 and the clamping block 280 are driven by the inclined surface 300, so that the clamping block 280 slides along the guide groove 270. The clamping block 280 cooperates with the side wall of the positioning groove 110 to clamp the camera 150, preventing the camera 150 from dislodging from the positioning groove 110 when the needle seat 130 is pulled out from the connector 170 of the camera 150, thus preventing the needle seat 130 from being unable to be pulled out.

[0059] In some embodiments of this utility model, a spring 310 is also included. The spring 310 is located between the guide groove 270 and the clamping block 280. The spring 310 is used to drive the clamping block 280 to move away from the positioning groove 110.

[0060] It is understood that in this embodiment, by setting a spring 310, the clamping block 280 is moved away from the positioning groove 110, so that the clamping block 280 is moved away from the camera 150, thereby resetting the clamping block 280 and releasing the clamping block 280 from clamping the camera 150, so that the camera 150 can be taken out from the positioning groove 110.

[0061] In some embodiments of this utility model, a coaxial cable 320 is included, with a first plug 350 and a second plug 360 at both ends. The coaxial cable 320 is connected to an external testing device through the first plug 350. A socket 370 is provided on the side of the adapter circuit board 120 away from the pin seat 130, and the second plug 360 is connected to the socket 370.

[0062] Understandably, since the coaxial cable 320 can move frequently with the moving part 140, and the coaxial cable 320 is flexible, the coaxial cable 320 is not easily damaged during the process of the moving part 140 driving the adapter circuit board 120 away from or near the support base 100, which helps to improve the service life of the test fixture.

[0063] In addition, the coaxial cable 320 is connected to external testing equipment through the first plug 350, and the second plug 360 can be plugged into the socket 370. Furthermore, after the movable part 140 moves closer to the support base 100, the second plug 360 is positioned upwards, making it less likely for other parts to interfere with it, and the coaxial cable 320 is also easier to assemble and disassemble.

[0064] It should be noted that the 320 coaxial cable is available for purchase on the market, and will not be discussed further here.

[0065] This embodiment also proposes a testing device, referring to... Figure 6It includes the aforementioned camera 150 test fixture and test box 330, with the test box 330 and the test fixture electrically connected.

[0066] It is understood that this embodiment sets up a camera 150 test fixture and a test box 330. The test box 330 has a connection port 340, and the first plug 350 of the coaxial cable 320 can be connected to the connection port 340, so that the data of the camera 150 is transmitted to the test box 330 through the test fixture, and the test box 330 performs the test. As a result, the number of circuit boards in the camera 150 test fixture is small, which can reduce manufacturing costs. In addition, the number of circuit adapters is small, which reduces the problem of loosening of circuit adapters caused by frequent contact between the test fixture and the camera 150. Thus, the risk of circuit non-conductivity is reduced and the transmission efficiency of electrical signals is improved.
